我想使用Azure在DocumentDB中创建一个集合。我有一个代码,但在执行时会抛出一个错误,说明"无法读取属性' _self'未定义"。 以下是我的代码,任何人都可以查看我的代码并帮助我。

app.js

var DocumentClient = require("documentdb").DocumentClient;

//the URI value from the DocumentDB Keys blade on http://portal.azure.com 

var endpoint ="https://somedbname.documents.azure.com:443/";

//the PRIMARY KEY value from the DocumentDB Keys blade on 

http://portal.azure.com 

var authkey = 

"SomeAuthKey=="; 

var client = new DocumentClient(endpoint,{"masterkey": authkey});

var databaseDefinition = {"id": "documentdb1"};

var collectionDefinition = {"id": "table1"};

var documentDefinition = {

        "id": "pgogula",

        "stuff": "Hello World",

        "bibbidi": {

        "bobbidi": "boo"

        }
};


client.createDatabase(databaseDefinition, function(err,database){

client.createCollection(database._self,collectionDefinition, 

function(err,collection){

client.createDocument(collection._self, documentDefinition, 

function(err,document){

client.queryDocuments(collection._self,"SELCT * FROM docs d WHERE 

d.bibbidi.bobbidi='boo'").toArray(function(err, results){

 console.log("Query Results:");

 console.log(results);

 });

});

});

});

错误:

client.createCollection(database._self,collectionDefinition, function(err,coll
                                ^

1 个答案:

答案 0 :(得分:4)

以下是一些提示:

  1. 查看您获得的例外情况:

    client.createCollection(database._self,collectionDefinition, function(err,coll ^ TypeError: Cannot read property '_self' of undefined

    database未定义,因为您收到传入回调的错误。看起来你收到的错误信息是:

    { code: 401, body: '{"code":"Unauthorized","message":"Required Header authorization is miss ing. Ensure a valid Authorization token is passed.\\r\\nActivityId: a98d9f51-982 a-450d-8bc1-f1a0ce5c7eb2"}' }

    错误消息表明客户端未能使用您的authkey对数据库请求进行签名。查看代码,客户端需要masterKey属性(注意驼峰式大小写)而不是masterkey。替换以下字符串将修复您的代码:

    var client = new DocumentClient(endpoint,{"masterkey": authkey});

    使用:

    var client = new DocumentClient(endpoint,{"masterKey": authkey});

  2. 公开发布您的身份验证密钥很危险 - 现在任何人都可以访问您的数据库。我强烈建议重新生成钥匙;从stackoverflow中删除它是不够的。

  3. 您在以下文档查询中有拼写错误,这将导致查询失败。请替换:

    client.queryDocuments(collection._self,"SELCT * FROM docs d WHERE d.bibbidi.bobbidi='boo'")

    使用:

    client.queryDocuments(collection._self,"SELECT * FROM docs d WHERE d.bibbidi.bobbidi='boo'")

  4. 这应该让您的代码正常工作;或至少它在我的电脑上完成:)
